COOLER F0 R MOTO R-VEHlC-LES SPECIFIGATION formng' part of Letters Patent No. 745,654, dated December 1, 1903- Application file October 18, 1901. Serial No. 79.083. (NO model.)

T0 all whom it may concrn: l

Be it known that I, RANsoM E. OLDs, aciti- .zen of the United States, residing at Detroit,

in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Coolers for Motor-Vehicles, of which the following is a specification, referencebeing had therein to the accompanying drawings. o

The invention relates to coolers for use in connection with heat-engines of motor-vehicles; and the invention consists in the peculiar construction, arrangement, and combination of parts, as hereinafter described and claimed.

In the drawings', Figure 1 is a longitndinal section through the body of a motor-vehicle, showing the motor and the arrangement of the cooler in connection therewith. Fig. 2 is a diagrammatic view illustrating the cooler system. i

It is one of the objects of the invention to arrange the radiator of the cooler in a position where it may be conveniently disposed and where it will be exposed to the full current of air caused by the motion of the vehicle.

It is a further object to utilize the heat of the radiator in warming the foothoard of the vehicle.

As shown, A is the vehicle-body, and B the motor arranged within said body. For this a gas or other heat motor isemployed, and to 'remove the superfiuous heat the cylinder is provided with a cooling-jacket C, through which water or some other cooling fluid is continuously passed. D is theradiator. This is preferably formed of headers a and b, connected by cross-tubes c, the proportion of parts being such that the ,radiator may be placed beneath the footboard d of the vehicle, with the headers arranged at opposite sides thereof. As the motor is arranged within the body and the radiator beneath the footboard, it is evident that a gravity circulation cannot be used for causing a Constant flow of the heated water from the jacket C to the radiator. To avoid this difficulty, a small pump, such asthe centrifugal pump E, is arranged in line with and connected to the crank-shaft of the motor, and this pump is then connected into the hot-water conduit leading from the motor to the radiator. As shown, the connecting-condnits are formed first by arranging a tank F immediately above the cylinderjacket, into which the hot waterA from the lat-.

ter rises. The tank F is then connected 'by a conduit G with the inlet-port of the pump E, while the outlet thereof is connected by a conduit H with the radiator. The opposite side of said radiator is connected by a conduit I with a port in the bottom of the cylinder-jacket. Thus when the motor is in operation a coolingfluid is forced to circnlate from the ;jacket toV the radiator and after being cooled in passing through the latter to return again into the jacket.

The arrangement of the radiator beneath the footboard of the vehicle-body has the advantage, first, that in this position the current of air caused by the forward movement of the vehicle will blow directly upon the radiator, thereby'greatly assisting in the dispersion of the heat. To increase this efiect, the forward endA of the dashhoard is preferably inclined, as shown, so as to direct a larger volume of air against the radiator, and

the radiator is preferahly formed in two separated Sections D' and D2, between which the current from the dashboard is directed. 'i

A further advantage of this arrangement of radiator is that a very large surface area may be obtained without occupying space available for any other purpose or interferin g with any of the mechanisxn of the vehicle and without changing the shape or appearance of the body. Still further, this arrangement of the radiator will keep the foothoard warm, and thus will be of value in warming the feet of the riders in cold weather.

What I claim as my invention is-- 1. In 'combination with a vehicle having a horizontally-disposed footboard, a motor on said vehicle, and means for cooling said motor,` including a horizontally-arranged radia- Io zontal alinement with the forward opening of the space between the Sections of the radiator to deflect currents of air into Said space.

In testimony whereof I affix my signature in presence of two witnesses.
